\(\varLambda \) CDM models for dark energy are proposed using various functional forms to represent different cosmological models and resolve the mysteries of the universe. In the present article keeping the concept of varying fine structure constant, two such basic models with function of scale factor are correlated to produce a common condition for the \(\varOmega _\varLambda \) , \(\varOmega _m\) , and \(\varOmega _{m0}\) . The novelty of this work is that it can unify two different models or create the common conditions which are very essential to solve such problems.

摘要

\(\varLambda \) CDM models for dark energy are proposed using various functional forms to represent different cosmological models and resolve the mysteries of the universe. In the present article keeping the concept of varying fine structure constant, two such basic models with function of scale factor are correlated to produce a common condition for the \(\varOmega _\varLambda \) , \(\varOmega _m\) , and \(\varOmega _{m0}\) . The novelty of this work is that it can unify two different models or create the common conditions which are very essential to solve such problems.
